This class will work on flat-fixing skills, suitable for all levels. Class will end around noon. We'll focus on how to reliably repair a flat tire and continue on your way. Leader will supply tubes for practice repair, you will be able to take home a patched tube to carry as a spare on your next ride. We're not actually riding anywhere (class will be held at Grand Army Plaza) but bring your bike so you can practice wheel/tire/tube removal. Please preregister and contact leader with your tire size and valve type so we can bring enough tubes of each size.
